Whatever is fluid, soft, and yielding will overcome whatever is rigid and hard. What is soft is strong.
LaoziIf princes and kings could follow it (Tao), all things would by themselves abide, Heaven and Earth would unite and sweet dew would fall. People would by themselves find harmony, without being commanded.
LaoziUnder heaven all can see beauty as beauty only because there is ugliness. All can know good as good only because there is evil. Therefore having and not having arise together. Difficult and easy complement each other. Long and short contrast each other. High and low rest upon each other. Voice and sound harmonize each other. Front and back follow one another.
Laozi
